I get bored quickly and haven't used it many times. I checked it for the listing, and there are no issues with the jack contacts, and no noise at all. I'm not sure about the USB port. There are traces of double-sided tape on the back. I seem to remember throwing away the box, so this is just the main unit for sale.
